This '''experiment''' by [[John Cockcroft]] and [[Ernest Walton]] is claimed by some physicists as demonstrating that ''[[E=mc2|E=mc<sup>2</sup>]]''.<ref>[http://cerncourier.com/cws/article/cern/31864 Mike Poole ''Cockcroft's subatomic legacy: splitting the atom''], Cern Courier, Nov 20, 2007</ref>

Conducted in April 1932 at the [[University of Cambridge]]'s [[Cavendish Laboratory]] in England, the physicists Cockroft and Walton successfully split [[lithium]] atom [[nucleus|nuclei]] by colliding them with artificially accelerated protons. This experiment is general hailed as being the first [[transmutation]] of an element using artificially accelerated particles, for which they were honored with the [[Nobel Prize]] in 1951<ref>[http://www.nobelprize.org/nobel_prizes/physics/laureates/1951/ ''The Nobel Prize in Physics 1951''], Nobelprize.org, 23 Jan 2013</ref>.
